Bearing, Thrust Roller Bearings, , Spherical Thrust Roller Bearing 811321
Characteristic of zinc
die casting products:
1. High specific density, more
strength than plastic injection molding.
2. Good casting performance, Producing complex shape and Thin-walled precision die casting
parts,
3. Easy do the surface treatment: Plating, powder
coating, Painting.
4. Do not attract iron when Melt and die casting, do
not corrosion Zinc Die Casting Mould and Non-stick mold.
5. Have good room temperature mechanical properties
and wear resistance.
6. Low melting point, Melts at 385℃, more easily forming
than aluminum alloy die-casting molding.
M Domestic commonly used
die-casting zinc alloy material performance:
The traditional
die-casting zinc alloy: No.2, No.3, No.5, No.7. ZA8 Currently the most widely
used is zinc alloy No.3.
The application of
commonly used zinc alloy:
No.2: It is used to those mechanical fittings that
have special need in mechanical capability, and need high rigidity and normal dimension and precision.
No.3: Good liquidity and
mechanical properties, and the best combination of mechanical properties, casting properties and
economical. It applied to the die casting part which the mechanical strength requirement
is not high. Such as toys, light parts, decorations and part of the electric
parts.
No.5: Good fluidity and
good mechanical properties, high wear resistance. It applied to the zinc die
casting part which has requirements of mechanical strength. Such as auto parts,
mechanical and electrical parts, machinery parts, electrical components.

Descriptions on LZWB spherical thrust roller bearing :
Thrust spherical roller bearings for axial load mainly axial. Meridional joint load, but after the load should not exceed 55% of the axial load. With the other thrust roller bearings, such bearings lower friction coefficient, high speed, and with self-aligning capability. 29000 roller bearing asymmetric spherical roller, can reduce the stick and the raceway at work relative sliding and roller length. Diameter, roller quantity load capacity, often using oil lubrication, individual low speed can be greased. In the design selection should be preferred.
Thrust Roller Bearings are available with cylindrical or spherical rollers. These bearings sustain only axial loads, but have high axial rigidity and are suitable for heavy loads. They contain convex rollers, have a self-aligning capability and are free of any influence of shaft deflection or mounting error. Standard cages are machined brass, where the E-type offers a pressed cage for high load capacity.
